402F30711CDR Application Field and Working Principle

Crystal oscillators, also known as quartz or piezo oscillators, use a quartz crystal to create an oscillating electrical current. Quartz crystals are piezoelectric, meaning they produce a small voltage when subjected to mechanical stress. This voltage is amplified by a circuit and used to generate a steady frequency. The quartz crystal oscillator is an electronic component used in a wide range of applications where precise timing is required. This includes radio communications, navigation systems, and electronic instrumentation.

Applications

The 402F30711CDR crystal oscillator is a high-performance oscillator that is typically used in high-frequency applications. It is most commonly used in digital signal processing, clock and data recovery, spread spectrum clocking, and data communication. Its features include a frequency accuracy of 10 parts per million (ppm), a temperature range of -55° C to +85° C, and a low start-up current.

Operating Principle

The crystal oscillator works by using the mechanical properties of a quartz crystal to or generate a precise electrical signal. When exposed to an electrical current, the crystal undergoes a mechanical vibration. This vibration is known as the resonance frequency. By controlling the frequency of the input current, the crystal can be made to vibrate at a specific frequency.

The output of the crystal oscillator is then used as the timing reference for the other parts of the circuit. This can be used to generate a precise clock signal for timing operations or for regulating the speed of the clock in the system.

Conclusion

The 402F30711CDR crystal oscillator is a versatile component that can be used in a wide range of precise timing applications. It features a high frequency accuracy and wide temperature range, making it suitable for even the most demanding applications. The precise electrical signal generated by the crystal oscillator can be used to control the timing of various parts of the circuit.
